Select the occluded triangles, considering the given occluder AABB trees (which may represent more geometry than a single mesh) See simpler invocations below for the single instance case or the case where you'd like the spatial data structures built for you Selection will be stored in the RemovedT array, but no triangles will be removed.
true on success
